FAA Part 107 Drone Practice Test 2025 – 400 Free Practice Questions to Pass the Exam

The floor of the Savannah Class C airspace at the outer circle is designated as 1,300 feet MSL (Mean Sea Level). This altitude indicates that the airspace begins at 1,300 feet above sea level, allowing for controlled air traffic operations while providing a buffer for other aircraft at lower altitudes. Class C airspace generally has a two-tiered structure with an outer shelf, and the vertical limits are specifically defined to manage traffic effectively around major airports. In this case, understanding that MSL is the standard for measuring airspace indicates the beginning of controlled operations in the outer circle of the Savannah Class C airspace.

The other options mention elevations related to AGL (Above Ground Level), which are not applicable in this context since the question is specifically regarding the MSL altitude for the Class C airspace floor. Therefore, recognizing that Class C airspace limits are specified in relation to MSL is crucial for pilots when navigating and planning their operations in and around controlled airspace.
